Legal Disclosure –

Additional Information

This presentation is not an offer to purchase or a solicitation of an offer to sell securities of

Baker. On September 9, 2013, Integrated Mission Solutions (IMS) filed with the Securities

and Exchange Commission (the “SEC”) a tender offer statement on Schedule TO (the

“Schedule TO”) and Michael Baker Corporation (“Baker”) filed with the SEC a

Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9)

regarding the tender offer by IMS for all of the outstanding shares of common stock of

Baker. On September 9, 2013, IMS mailed to Baker’s shareholders the Schedule TO, which

included an offer to purchase and related materials (including materials specifically related

to participants in Baker’s 401(k) Plan), and Baker mailed to its shareholders Schedule 14D-9,

with respect to the tender offer. Baker shareholders are urged to read these materials (and

any

amendments

updates

thereto)

carefully,

since

they

contain

important

information,

including the terms and conditions of the offer, that Baker shareholders should consider

before tendering their shares. Baker shareholders may obtain a free copy of these materials

and other documents filed by IMS or Baker with the SEC at the website maintained by the

SEC

www.sec.gov.

materials

also

Cautionary Note with Respect to Forward-

Looking Statements

This presentation contains forward–looking statements with respect to the tender offer

and related transactions, including the expected timing of the completion of the tender

offer

and

transactions.

When

used

this

presentation,

the

words

“can”,

“will”,

“intends”, “expects”, “is expected”, similar expressions and any other statements that are

not historical facts are intended to identify those assertions as forward-looking statements.

Such statements are based on a number of factors that could ultimately prove inaccurate,

and are subject to a number of risk factors, including uncertainties regarding the timing of

the

closing

the

transaction

and

the

risk

that

the

transaction

will

not

close.

Factors

that

could cause actual results to differ materially include the following: the risk that a majority

of Baker shares are not tendered in the tender offer, the risk that Baker experiences a

material adverse change giving IMS the right not to close the transaction, the risk that IMS

is unable to close on its financing and the risk that Baker’s business will suffer due to

uncertainty related to the transaction, the competitive environment in our industry and

competitive responses to the transaction. Baker does not assume any obligation to update

any forward-looking statement, whether as a result of new information, future events or

otherwise. Further information on factors that could affect Baker’s financial results is

provided in documents filed by Baker with the SEC, including Baker’s recent filings on Form

10-Q and Form 10-K.

Additional Reminders and

Thoughts

Some other things to remember and think about

401(k) Plan –

Additional Reminders

Baker will continue to provide company

matching contributions:

100% on first 3% of employee contributions.

50% on second 3% of employee contributions.

All future matches will be 100% cash and

placed in funds as directed by the employee.

After the transaction there will no longer be

Baker stock in the 401(k) Plan.

Employees are responsible to move

transaction proceeds from the appropriate

Retirement Date Fund.

401(k) Plan –

Additional Reminders

All of these transactions will be free of tax or

penalty since they will occur within the 401(k)

Plan.

Employees should check their 401(k) account

balances before and after the blackout period

to validate that balances are correctly

reflected in your account.

401(k) Plan –

Additional Reminders

All employees are encouraged to update

beneficiary information with TRP!

Only 37% of employees have listed

beneficiaries.

Failure to name a beneficiary could create

significant problems if something happens to

you.

Updating beneficiaries in Oracle during open

enrollment DOES NOT update the information

with TRP!

ESPP –

Additional Thoughts

Employees are responsible for the taxes

related to the sale and disposition of shares

and dividends from the ESPP.

Short term gains will be recorded as income

on employees’

W-2s.

AST will provide a Form 1099 to employees at

year end for tax purposes (Long Term Capital

Gains).

Employees are encouraged to consult with a

tax advisor related to these topics.
